best ever hot cocoa recipe

I love getting crafty and I love it even more when I'm paid to do it. Everyone is working on projects at the office (it's slow season) and I offered to make some gifts for agents, attorneys and clients. There is always a lot of baked goods going around and it is so hard not to eat cookies and donuts when they are sitting around the office all day. 
I wanted to do something cute that can be taken home and used over time.  I decided to come up with my own recipe for hot cocoa and put the mix in mason jars. 
The best hot cocoa recipe ever:
2.5 cups instant non-fat milk 1 cup cocoa powder 2 cups powdered sugar 1 teaspoon corn starch 1 teaspoon salt 2 pinches of cinnamon pinch of cayenne pepper
Mix ingredients well and store in air-tight container. To serve, mix with hot water. I preferred about 2 tablespoons of cocoa to water ratio, Joe likes his more like 2 to 1 water to cocoa.
Top with marshmallows and miniature chocolate chips for fun!
